Make a separate ssh key for your phone with restricted sftp-only access to a phone-specific backup directory on your server.
- hsivonen 9y agoWhat's a good tutorial for restricting sftp access to a particular directory? (Assuming the same host supports ssh login, too.)
- jstimpfle 9y agoAssuming openssh-server, look for "internal-sftp" in sshd_config(5). And of course, also google a bit around that. It's worth pointing out that this will preclude use of rsync and similar tools that require running a server on the remote machine. I'm not aware of robust alternatives so if anyone else knows one please tell me! (and I consider rsync-restricted shells and similar approaches a hack)
